Is your charity / foundation website keeping up? Here's what the data shows.

Charity / Foundation Website Audit Report

We scanned 323 charity / foundation websites across the United States to benchmark their performance for search engines, AI answer engines, and accessibility.

Industry: Nonprofit · Sample size: 323 sites · Scan date: March 14, 2026

Overview

The charity / foundation industry faces a clear challenge online. Most websites in this space score well below what search engines and AI systems need to surface content. The average AISO score across all 323 sites is just 44 out of 100. That is a low bar. It also means there is a big opportunity for businesses that invest in their web presence now.

The strongest area for charity / foundation sites is SEO, with an average of 68. The weakest area is AEO, at just 12. According to Google's SEO documentation, sites that fail to meet basic technical standards risk losing visibility in both traditional and AI-powered search results.

What does this mean for your business? If your site scores above 44, you are already ahead of most competitors. If it scores below, you risk losing traffic to rivals who fix these issues first. According to the W3C Web Accessibility Initiative, accessible websites also reach a wider audience and reduce legal risk.

Key insight: 79% of charity / foundation websites score below 50. The majority of sites in this vertical are underperforming across multiple dimensions.

Score Below 50

More than half of sites in this vertical are underperforming.

37%

Missing Schema Markup

These sites have no structured data, making them harder for search engines and AI to understand.

19%

No Open Graph Tags

Without OG tags, shared links on social media appear without rich previews.

What This Means

These findings tell a simple story. Most charity / foundation websites were built without modern optimization in mind. They load, they look fine, but they fail to communicate with the systems that drive traffic today.

Search engines need structured data to understand your pages. AI answer engines need clear, direct answers to cite your content. Screen readers need proper HTML to serve users with disabilities. Missing any of these means missing out on visitors, customers, and revenue.

Key Takeaways

After analyzing 323 charity / foundation websites, here's what stands out most. These are the three most important points from the data.

  1. Most sites score poorly overall. An average AISO score of 44 means the typical charity / foundation website misses more than half of what modern search and AI systems look for.
  2. AEO is the weakest link. At just 12 on average, this dimension drags down overall scores. Fixing it first gives the biggest return.
  3. Basic technical issues are widespread. 37% of sites lack schema markup. 19% have no Open Graph tags. These are quick wins that most sites have not addressed.
Bottom line: The charity / foundation industry is behind on web optimization. Early movers who fix these issues will gain a real edge in both search rankings and AI visibility.

How to Improve Your Score

Want to beat the average? Follow these steps in order. Each one builds on the last. Start with the basics and work your way up.

  1. Step 1: Fix your technical SEO. Add a meta title, meta description, and canonical URL to every page. Add schema markup using JSON-LD. Add Open Graph tags so your links look good when shared. These changes take less than an hour and have an immediate impact.
  2. Step 2: Improve readability. Rewrite your main pages at an 8th grade reading level. Use short sentences. Use simple words. Break up long paragraphs. According to Google, clear and simple content performs better in search results.
  3. Step 3: Add engagement elements. Use headings, bullet lists, bold text, and blockquotes. Add images with descriptive alt text. Make your content easy to scan. Visitors decide within seconds whether to stay or leave.
  4. Step 4: Optimize for AI engines. Add a FAQ section to your key pages. Use direct answer formats. Define what your business does in one clear sentence at the top of your homepage. AI systems like ChatGPT and Perplexity prefer content that gives a straight answer.
  5. Step 5: Check accessibility. Run a WCAG audit. Ensure all images have alt text. Check that color contrast meets minimum ratios. Use semantic HTML elements like headings, lists, and landmarks. According to the W3C, over one billion people worldwide live with some form of disability.

Methodology

We score each website across five areas. The AISO Score is a weighted mix of all five. It shows how well a site works for both people and AI systems. Here is what each area measures.

SEO (Technical Search Optimization)

Checks meta titles, descriptions, canonical URLs, schema markup, Open Graph tags, heading structure, and other signals that help search engines crawl and index a page.

Readability

Measures the Flesch Reading Ease score, average sentence length, and word complexity. Higher scores mean the content is easier for the public to read and understand.

Engagement

Looks at content formatting: headings, lists, bold text, blockquotes, images, and other elements that make content easy to scan and read.

AEO (AI Engine Optimization)

Checks how well content is set up for AI answer engines like ChatGPT, Perplexity, and Google AI Overview. Looks for direct answer formats, FAQ sections, and clear definitions.

WCAG (Accessibility)

Tests for Web Content Accessibility Guidelines compliance: color contrast, alt text, ARIA labels, semantic HTML, and keyboard navigation support.
